Micromyrtus trudgenii is a species of flowering plant in the family Myrtaceae and is endemic to a small area of inland Western Australia.

It is an erect, open shrub with narrowly egg-shaped leaves with the narrower end towards the base, and yellow flowers with 10 stamens.

[2][3] Micromyrtus trudgenii was first formally described in 2007 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Joseph Zvonko Weber west of Paynes Find in 1975.

[2][4] The specific epithet (trudgenii) honours Malcolm Eric Trudgen.

[3] Micromyrtus trudgenii is listed as "Priority Three"[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
